PROMPT自定义实践
官方给出有4种方式可以实现命令行自定义。
1、调整系统环境变量，使用MYSQL_PS1
[mysql@zsdb script]$ export MYSQL_PS1="(\u@\h) [\d]> " <=======MYSQL_PS1 [mysql@zsdb script]$ ./m3306.sh 。。。。。。。 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. (root@localhost) [(none)]> use mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed (root@localhost) [mysql]>
2、在mysql命令使用--prompt参数
[mysql@zsdb script]$ /u01/mysql5.7/svr/bin/mysql --prompt="(\u@\h) [\d]> " -uroot --socket=/u01/mysql5.7/run/my3306/mysql.sock -p123456 。。。。。。。 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. (root@localhost) [(none)]> use mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed (root@localhost) [mysql]>
3、编辑*.cnf文件，添加prompt选项
[mysql]
prompt=(\\u@\\h) [\\d]>\\_
[mysql@zsdb script]$ ./m3306.sh 。。。。。 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. (root@localhost) [(none)]> use mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed (root@localhost) [mysql]>
4、sql交互窗口使用prompt
[mysql@zsdb script]$ ./m3307.sh 。。。。。。 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> prompt (\u@\h) [\d]>\_ <======= 参数调整 PROMPT set to '(\u@\h) [\d]>\_' (root@localhost) [(none)]> use mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed (root@localhost) [mysql]>
